Abstract
Abstract Apparatus for accurately positioning and retaining multiple, individual reagent test devices in a holder. The holder consists of a base member and a top member in which the top member contains openings of at least the same number and dimension as the reagent pads appearing on the test devices. The holder permits the practical utilization of multiple, individual dip-and-read test devices in automated instrumentation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
239 words
Apparatus for simultaneously making multiple analyses of liquid fluid, which apparatus comprises in combination: multiple, separate, dip-and-read reagent test devices, each consisting essentially of one carrier matrix pad, having reagent incorporated therein, attached to the upper surface of one end of an elongated, flexible substrate, wherein each said carrier matrix pad is raised to a height substantially above the surface of the substrate to which said matrix pad is attached; and reagent test device holding means for accurately positioning and retaining said carrier matrix pads of the reagent test devices immobile during analyses, said reagent test holding means consisting essentially of a base member for retaining said reagent test devices in parallel alignment, a separate top member containing openings substantially identical in size, number and configuration to the carrier matrix pads, hinge means for interconnecting the base member and the top member wherein the openings of said top member are in registry with each carrier matrix pad of said reagent test devices such that the reagent pads project into said openings so as to immobilize and isolate each carrier matrix pad during the analysis of a liquid fluid and substantially eliminate runover from occurring between adjacent carrier matrix pads on the reagent test devices, wherein said reagent test device holding means is constructed of a rigid, cleanable material of thickness such that the openings in said top member form wells into which liquid fluid to be analyzed is placed.

Claim 3
Dependent Claim
15 words
The apparatus of claim 1 in which the reagent test device holding means is plastic.
Claim 4
Dependent Claim
27 words
The apparatus of claim 1 in which the means for interconnecting the base member and top member of said reagent test holding means is a piano hinge.
Claim 5
Dependent Claim
243 words
Apparatus for simultaneously making multiple analyses of liquid fluid, which apparatus comprises in combination: multiple, separate, dip-and-read reagent test devices, each consisting essentially of a plurality of carrier matrix pads having reagent incorporated therein, attached to the upper surface of an elongated, flexible substrate in a horizontally spaced manner, wherein each said carrier matrix pad is raised to a height substantially above the surface of the substrate to which said matrix pad is attached; and reagent test device holding means for accurately positioning and retaining said carrier matrix pads of the reagent test devices immobile during analyses, said reagent test holding means consisting essentially of a base member for retaining said reagent test devices in parallel alignment, a separate top member containing openings substantially identical in size, number and configuration to the carrier matrix pads, hinge means for interconnecting the base member and the top member wherein the openings of said top member are in registry with each carrier matrix pad of said reagent test devices such that the reagent pads project into said openings so as to immobilize and isolate each carrier matrix pad during the analysis of a liquid fluid and substantially eleminate runover from occurring between adjacent carrier matrix pads on the reagent test devices, wherein said reagent test device holding means is constructed of a rigid, cleanable material of thickness such that the openings in said top member form wells into which liquid fluid to be analyzed is placed.
